Introduction

A CircuitPython helper for encoding/decoding MIDI packets over a MIDI or UART connection.

Dependencies

This driver depends on:

• Adafruit CircuitPython

Please ensure all dependencies are available on the CircuitPython filesystem. This is easily achieved by downloading the Adafruit library and driver bundle.

Installing from PyPI

On supported GNU/Linux systems like the Raspberry Pi, you can install the driver locally from PyPI. To install for current user:

pip3 install adafruit-circuitpython-midi

To install system-wide (this may be required in some cases):

sudo pip3 install adafruit-circuitpython-midi

To install in a virtual environment in your current project:

mkdir project-name && cd project-name
python3 -m venv .env
source .env/bin/activate
pip3 install adafruit-circuitpython-midi

Usage Example

import time
import random
import usb_midi
import adafruit_midi

midi = adafruit_midi.MIDI(midi_out=usb_midi.ports[1], out_channel=0)

print("Midi test")

print("Default output MIDI channel:", midi.out_channel + 1)

while True:
    midi.note_on(44, 120)
    midi.note_off(44, 120)
    midi.control_change(3, 44)
    midi.pitch_bend(random.randint(0,16383))
    time.sleep(1)
